Without the addition of batteries, these solar grids would only supply power when the sun was shining. The batteries can supply power during outages and at night, and help “shave” energy bills by supplying energy at peak demand hours, when utility costs are highest.

Ideal Energy is currently building a large, 1.1 megawatt solar array with a 1.1 megawatt hour vanadium flow battery for the Maharishi University of Management in Fairfield. This is the largest solar plus project in the state of Iowa and will cover about a third of the university’s annual energy needs.

Ideal is also installing a somewhat smaller array with a lithium-ion battery at the Agri-Industrial Plastics Company in Fairfield. The battery will provide nighttime power for the company’s 24-hour production lines and save them an estimated $42,000 annually.

With the Iowa Economic Development Authority grant, Ideal will assess and compare the performance, efficiency and maintenance of both systems in partnership with Iowa State University’s Electric Power Research Center. A statewide committee, established by the 2016 Iowa Energy Plan, will evaluate the research to inform future solar plus projects in the state.
